T @ZZ whom t may concern.'

Be it known that I, JULES MENU, a citizen of the AKingdom ot Belgium,.residing at 11 Passage, de lElysee des Beaux-Arts, Paris, in the Republic of France,have invented certain new-and useful'lmprovements in .Mud- Guards, Vof Whichthe following-is a speciiication.

. The invention has for its object Yimprovement-s in the construction and in the means for mounting-and fixing `to vehicle Wheels,

' mud guards of the type ofV those in which the annular. crown .forming the screen Vis fixed to the Wheel and rotatesWith it.

v:in accordance with the invention, the annular screen or :mud guard proper is mounted upon a false metal rim of appropriate sectionto insure'rigidity and which lits the rim ofthe Wheel and isk detachably ixedrto the Wheel, preferably to the rim of the latter, in such a manneras to torni, so to speak an external extension of thisrim in constitutingk a rigid cylindrical itting or frame protecting the screen fromV external shocks. For example this -italse rim is most advantageously constituted likeV a metal pneumatic tire rim, preferably like a hooked Y or channeled rim for beaded tires with this vannular ring is fitted at itsv inner side upon the; rim 'ot' the wheel upon which' it is mount- .ed and it is detachably ixed'inthis positionV by appropriate'means. A Finally the invention relatesto devices for engaging and locking' the ,false rimupon "the Wooden Wheel rim, which permit of a particularly simple and 1 apid mounting;and dismountinfr. -`Theaccompanying,drawings show by way A.of example' a method of carrying the invention into practice in thethree casesV ot' 4a Wooden Wheel, of a metal Wheel and finally of a lorry or motoromnibuswheeh but it should;` be clearly understood that this is `merely. byfWay-otjenample and that 4both the form oi the false rim and of the annular screen .i cross section, and the means for hringthe raise rim to the Wheel may vary,

the main idea being to provide a false rim ,v

which protect-s the screen and which tits the Wheel rim in such a manner as to acquire the rigidity of the Wheel.

Figures l to G represent a constructional form particularly applicable to Wooden Wheels for pneumatic tires; Figs. l and 2 are' a cross section and a partial plan, respectively, of the mud guard mounted upon the u'heel, Figs. 3 and l are similar views showing the mud guard separately, Figs. 5 and show in det-ail in section and in plan, respectively, o'ne orn the lugs vfor fixing the false rim to the Wheel rim with its locking device. F '7 shows in cross section means 'for fixing the rim particularly applicable to metal Wheels tor pneumatic tires. Finally Fig. 8 shows the same type of mud guard mounted upon a motor omnibus wheel with protruding metal rim. i i In the construction shown in Figs. l to 6 the iiexible ring or mud guard screen l which may be constituted, for example, by a portion of a Worn or discarded 'pneumatic tire, is mounted (Figs. 3 and d) upon a falserim 2 similar to the metal rim S of the Wheel but comprising a single hook or retaining flange t in which the beading 5 of the ring l engages exactly in the usual manner. The fixing of the ring` l upon the false rim 2 is eliected by means ot' asuitable number of small angle pieces or lugs 6. One arm 6 of each of these angle pieces bears against the inner edge of the beading-5 While the other arm 6" is {iXed by means of screws and nuts 7 or in some other convenient manner to the false rim 2.

The mud guard this constituted can be fitted (Figs. and 2). to the inner lface ot the metal wheel rim, the inner edge 2 ot' the false rim iitting upon closely against the 'metal Wheel rim in the angle formed by the inclined surface 3 of the latter and the lateral Wall of the wooden rim or telly.v In order that the false rhin-which is of substantially the saine diameter as the wheel rim, may it the latter, its inner odge 2 is pressed slightly conical in such a manner as to iit exactly the surface 3. The centering and the strength or' the assemblage are thus realized in the most simple and expeditious manner merely by the angular fitllO . ting ofthe metal rim and the wooden wheel rim.

The fixing ofthe mud guard upon the wheel is ei'ected vby means of engaging lugs or brackets 10, a suitable number of which are distributed over the periphery of Vthe false rim .to which they are fixed by means of rivets 11er-otherwise. Each'of these lugs rvor brackets has a double bend to prof Y vide a portion adapted to overlie the inner sideof the wheel rim'or felly,` said portion being channeled or slotted as at 13 to engage studs 14,I having heads 15 and mounted on mentv of the mud guard thus mounted on 21 in Vwhich 'the collar 22 of' base or bearing plates 1G which are secured Y as by screws 17'to the wheel rim or felly. In order to engage the mud guard, it is only necessary, after pressing it laterally in posit-ion upon the.= wheel rim, to rotate it in its plane in the proper direction in such a. manner as to engage its slots 13 with the studs 14 fixed to the rim. Y

. In order to prevent accidental disloc the wheel, a locking'device constituted in the following manner is provided: One of the studs 14 (or several of them) is replaced (Fig. 5) by a' threaded rod 14 fixed in a similar manner to the rim by means ofa plate 16and.of screws 17 and thebottom of` the Achannel 13 formed in thecorrespondpresents a'circular portion of greater width engages. A Grover washer 24 can be inter# posed between the base of the nut 23 and theV luglO to prevent accidental loosening ofthe nut. Vhen the mud guard has been fitted to the wheel, in order VtoV lock itV it is only necessar to screw the wine` nut noon the threaded rod, the collar V22 engaging in the f slot 21 and locking the whole. The unscrewing or the screwing of a single nut through a few turns is thus sufficient topermit of removing or fitting the mud guard, so that these operations can be effected with the greatest` rapidity.' y Y This method of fixing bymeans of a bay- 'l onet joint is Vparticularly advantageous from vinterval between the spokes.

and which, while being easy to effect and very secure, eliminates any necessity for adjustment of the wheel with the mud guard and enables the mud guard to be despatched Vready for fitting to the wheel without any preliminaryV operation. Upon the periphery ofthe false rimY a suitable number offangle ing'engaging lug 10 represented in Fig. '6

wing nut V23 `pieces30 are arrange-d,- threeor` fourbeing V clainpfis bent'hook-shaped and ends in a portion 35 which follows the contour of the Y back of the hook or channelvof the. metal wheel rim. A nut 36 which is preferably Vlocked by a Grover washer 37 produces the f wheel. Y

Fig; Svrepresents the adaptation of the same: constructional form ofthe'invention as that described above to alorry or motor omnibus wheel withjprotruding metal rim. In't'his case the'rfalse rim 2 is adapted :to the outer periphery of the protrudingr v'metal rim 40, preferably sufliciently in retreat relatively to the outer edge thereof tol be afforded protection fromv external shocks. The fixing of the false rim' 2 to ,the wheel rim .40V can be effected by any convenient means for example by means of a bayonet joint, either Ysimilar to that represented in Figs. 1 to n6 or not,'or else as 'represented in F ig. 8 by means of lixingj bolts 41 the head V42 of `which is preferablyzarranged suffi-Y ciently close tothe tire' 43 orto .the arm 6 ofthe angle piece t'o be prevented from turning, thelock nut 44 being secured from accidental'YY unscrewingyby anyk convenient -nleans sueh'as a vGrrover washer, a pin 01- ,the
